Seamless Carbon Steel Tubing, Up To 3420 PSI

Description & Features

Application	Please review important safety & application information starting on
Note	A 6:1 safety factor is used in table below for applications where “considerable” hydraulic shock and mechanical strain are present. For applications where hydraulic shock and mechanical strain is not considerable, a 4:1 safety factor (higher working pressures) may be carefully considered. For applications where hydraulic shock and mechanical strain is severe, an 8:1 safety factor (lower working pressures) should be applied. Tubing design pressures have not been de-rated for elevated operating temperatures. Contact us for application information regarding elevated temperatures. Tubing is stocked in 20 foot nominal lengths.
Pressure Rating	Based on SAE Specification J1065 and using the more conservative Barlow formula where P=(2TxS)/O (P=burst pressure T=wall thickness S=tensile strength O=outside diameter).
Tubing Material Specifications	SAE J524 (seamless low carbon steel tubing annealed for bending & flaring). Tensile strength 55,000 psi.
Warning	Refer to safety information regarding proper selection of tubing and tube fittings starting on

Product Questions & Answers (1)

Question by: Floyd M on Sep 17, 2025, 10:29 AM

What kind of steel is this tubing made from, and will it hold up to bending without cracking?

Answer by: Customer Support on Sep 19, 2025, 8:33 AM

This seamless carbon steel tubing is manufactured to SAE J524 specifications. The material is a low carbon steel, and it's annealed specifically for bending and flaring, so it should hold up well.
